Instructions

  • Make a new wiki titled 14-4 Stoichiometry pt 2.
  • For 3 total problems (choose randomly so I know you didnt copy) show your work by showing how to set up the problem and giving the answer.
    • Put these 3 problems at the top of your page
  • For all the rest of them, just give the full answer after doing the work on scrap paper.
  • Example: how many grams of Na will 15 moles of NaCl produce? 2NaCl --> 2Na + Cl2
    1. (put the 4 parts here)15 mol NaCl/2 mol NaCl = x g Na/2 mol Na
    2. (put the substitution amount here) 2 mol Na = 45.98 g Na
    3. (put the answer here ) X = 344.85 g Na
  • Round all answers to 2 decimal places.

Using the combustion equation of C10H8 + 12 O2→10 CO2 + 4 H2O …

  • 1.How many moles of H2O does 5 moles of C10H8 make?
  • 2. How many grams of H2O does 5 moles of C10H8 make?
  • 3. How many moles of CO2 are made by 32 grams of O2?
  • 4. How many liters of CO2 are made by 3 moles of C10H8?
  • 5. How many grams of H2O are made by 1500 grams of C10H8?
  • 6. How many grams of C10H8 are needed to make 40.3 moles of H2O?

Using the single replacement reaction of 2 AgNO3 + Zn → 2 Ag + Zn(NO3)2 …

  • 10. How many grams of zinc to you need to make 5000 g of Zn(NO3)2
  • 11. If you use 1000 grams of Silver Nitrate how many g of silver will you make?
  • 12. (Use the answer from the previous question to help.) If a 1000 grams of silver nitrate cost $1385 (and it does), how much would it cost you to make the amount of silver from the previous question? ($X/$1385 = previous answer/1000g.)
  • 13. If you spill only 5 grams of silver nitrate, how much did that error cost you? (pay up fool!)
  • 14. How many moles of Zn(NO3)2 does 50 g of Zn make?

Using the Decomposition equation of 2 H2O → 2 H2 + O2 …
